Summary: Exposure to traffic-related air pollutants, such as NO2 and O3, can have detrimental health effects and is a major global public health issue. Exercising in polluted environments may be harmful to health and impede exercise training adaptations. This study aimed to investigate the effects of physical activity and O3 exposure on redox status, inflammatory markers, stress response, and pulmonary toxicity in young, healthy individuals. The results showed that physical activity was associated with higher O3 exposure, but not with age or markers of body composition. Individuals with high physical fitness and lower O3 exposure had better antioxidant defense, lower inflammation, and reduced pulmonary toxicity.

Summary: Studies have shown that long-term exposure to PM2.5, NO2, and O-3 is associated with a higher prevalence of obesity in children and adolescents, with stronger effects observed in males, regions with low economic levels, and specific age subgroups. Continuous efforts to reduce air pollution levels may help alleviate the increasing prevalence of obesity within a region.

Summary: Both air pollution and physical inactivity contribute to the increased risk of chronic kidney disease (CKD). Higher exposure to air pollutants during exercise can further amplify the detrimental effects of air pollution. This study analyzed data from nearly 368,000 participants and found that high levels of air pollutants (PM2.5, PM10, NO2, and NOX) increased the risk of CKD, while moderate and high physical activity reduced the risk. The findings suggest that increasing physical activity may help prevent CKD regardless of air pollution levels.

Summary: This study found that travelers in Zhengzhou tend to choose indoor commuting modes on polluted days due to traditional cultural influences. Personalized pollution exposure information can further reduce the rate of active commuting, but also leads to an increase in automobile commuting.

Summary: This study aimed to investigate the independent and interaction effects between long-term exposure to PM2.5 and physical activity on blood pressure and hypertension. The results showed that physical activity can decrease blood pressure and hypertension risks, while PM2.5 has the opposite effects. Furthermore, PM2.5 can attenuate the beneficial effects of physical activity on blood pressure and modify the association between physical activity and the risk of hypertension.

Summary: Long-term exposure to higher concentrations of PM1, PM2.5, PM10, and O-3 increases the risk of insomnia symptoms. Moderate to high levels of leisure physical activity alleviate the harmful effects of air pollution on insomnia, while high levels of occupational and housework physical activity intensify such effects.

Summary: The study revealed that prenatal exposure to PM10 and PMcoarse had consistent associations with reduced lung function, while associations with postnatal exposure were less consistent. An increase in CC16 levels at age 4 was associated with improved lung function, but no significant associations were found between air pollution and CC16.

Summary: The paper explores the neighborhood effect averaging problem and its impact on assessments of individual exposure to air pollution, highlighting different manifestations of the problem for different social/racial groups. Non-workers are found to not experience neighborhood effect averaging, leading to potentially higher exposures while traveling, highlighting the importance of considering mobility in studies related to environmental disparities.

Summary: This study investigates the feasibility of detecting urinary biomarkers of volatile organic compounds (VOCs) exposure in community wastewater. The results show the presence of various metabolites related to chemical exposure, with community 1 having higher detections and VOC loadings, which are associated with manufacturing activities and vehicle emissions.

Summary: This study reveals that socially disadvantaged children in Texas are disproportionately exposed to higher levels of vehicular pollution in public school districts. These districts also have greater proportions of racial/ethnic minority, foreign-born, disabled, and socioeconomically vulnerable children. The findings emphasize the urgent need for mitigation strategies to reduce pollution exposure, especially in districts with higher proportions of socially disadvantaged students.

Summary: This study presents a framework for direct field-calibration of low-cost air pollution sensors using probabilistic gradient boosted decision trees (GBDT). The results show that the probabilistic GBDT model improves point and distribution accuracies compared to linear regression models, particularly at high concentrations and on monitors not included in the training set. The study also demonstrates the use of the GBDT model in conducting probabilistic spatial assessments of human exposure on a neighborhood level.

Summary: A model combining statistical and agent-based modeling is proposed to assess long-term and large-population exposure to air pollution by treating mobility-related variables as random variables. Probability distributions for these variables are estimated or derived from mobility datasets. An exposure model is implemented on top of the activity model, using hourly air pollution maps for exposure assessment.

Summary: The possible role of fatty acid translocase (CD36) in the treatment of obesity has gained research interest. CD36 deficiency has complex effects on insulin signaling, depending on different nutritional stresses. This study investigated the effects of CD36 deletion on insulin signaling in C2C12 myotubes with or without palmitic acid (PA) overload. The findings suggest that CD36 is essential for insulin action maintenance and its deletion can improve insulin signaling under PA overload conditions.
